money, money, money

Why does everything in this world have to cost money?
I have enough money to live another 3 months, maybe 4 but then I'll be out of money. I'm not stable enough to have a job, I don't have any kind of income, only expenses. Rent, food, insurances, etc.

Wouldn't it be better for everyone if I would just kill myself now. It's not like I want to live anyway, I've just been living for others. But I'm not of any help to others if I can't even live properly.
Wouldn't it be better for me to die now, as I still have a bit of money? Then I can at least be of some kind of help to my friends, as they could get the little bit of money I DO have left.
